Promoter Selector-aeBlue

This part is promoter 2 (BBa_K1084002) constructed as Promoter Selector vector expresses aeBlue (Blue).

iGEM HokkaidoU Japan 2013 original promoter family is constructed from consensus promoter (BBa_K1084001) by adding mutation at -35 region. Other region is same among family members, and similar with promoter consensus sequence.

t. e. = theoretical transcription efficyency

Promoter transcription efficiency was measured with mRFP1 (BBa_K1084401-K1084410), LacZ and Kanamycine (Km) resistance (BBa_K1084501-K1084505).

Fig. 5 Comparison of assay results and modeling data

Theoretical promoter modeling also has done (see promoter Background page in HokkaidoU 2013 wiki). According to protein, these promoters show relatively another protein activity revel. Choose your best promoter by Promoter Selector. Plate image below is actual worked Promoter Selector (Km resistance).
